You sound like a programmer is only allowed to use one language. Where I work we have legacy systems in Cobol and new development in Java, some Android work, and we're Web Applications. All these need maintenance on occasion and having potential job candidate come in with some Cobol experience gives them a leg up on everyone else, it doesn't mean that Cobol is the only thing they are going to work in.
Just because I know how to use a hammer doesn't mean I can't learn how to use a wrench. Programming languages are tools, the more tools you know the more you can do,
